Definitions

  • the present invention relates to a vehicle having a transmission and a clutch arrangement according to the preamble of claim 1.
  • Vehicle clutches can be differentiated according to whether they are closed or opened when not actuated. Clutches which are closed in the non-actuated state are also referred to as “normally-closed clutches", clutches which are opened in the unactuated state are referred to as “normally-open clutches”. In most vehicles normally-closed clutch are used. In manual transmissions, the opening of the clutch is effected by an operating force introduced by the driver via the clutch pedal. In automated transmissions there are electrically controllable actuators, the so-called actuators. In the case of a normally open clutch, the clutch is opened in the unactuated state and must be closed with the force of the actuator and kept closed by the actuator.
  • the object of the invention is to provide a vehicle with a transmission and a clutch assembly in which the clutch requires no or only a comparatively low clamping force in the closed state.
  • the starting point of the invention is a vehicle having a transmission and a clutch arrangement, which has at least one clutch, a clutch actuator and a transmission device.
  • the clutch is a clutch that can be brought out of an unactuated opening state by applying an operating force or with an operating torque in a closed state.
  • the transmission device is intended to initiate a force generated by the clutch actuator or a torque generated by the clutch actuator as an actuating force or actuating torque in the clutch.
  • an "actuator coordinate" is converted into a "clutch actuation coordinate" according to a predetermined transfer function of the transmission device. Both coordinates can be forces, torques, displacement paths, rotation angles, pressures, etc.
  • the actuator coordinate need not necessarily have the same dimension as the clutch actuation coordinate, ie, the actuator coordinate may be, for example, a torque and the clutch actuation coordinate may be a force.
  • the clutch arrangement or the transmission device is designed such that the function of the Kupplungsbetuschistskoordi- on the actuator coordinate in the closed state of the clutch has a lower slope than in the open state and / or in the region between the opening state and the closing state. In this way, it is achieved that no or only a relatively small locking force or actuator force is required to lock the clutch, which has a favorable effect on the energy consumption of the vehicle.
  • the clutch assembly is thus not self-locking in the closed state, which has the advantage that in case of system failure, z. B. in case of power failure or generally in case of failure of the actuator, the clutch opens automatically.
  • the clutch assembly is self-locking in the closed state.
  • the clutch assembly is self-locking in the closed state.
  • partially actuated clutch d. H. if the clutch is not fully closed, it automatically goes into the open state in the event of a system failure. In the fully closed state, however, the clutch remains closed due to the self-locking even in the event of a system failure.
  • the functional course of the clutch actuation coordinate can be continuously and continuously differentiated via the actuator coordinate and has at least one inflection point.
  • an actuating force characteristic can be represented, in which the operating force for holding the clutch is very low, zero or even negative.
  • Negative in this context means that the clutch not only does not automatically open in the event of a system failure, but that one of the closing force or the closing torque is released to open the clutch. gene acting opening force or the closing torque counteracting opening torque must be applied.
  • the functional course of the clutch actuation coordinate can also be continuous but not continuously differentiable, the function curve in this case having at least one point or at least one section in which the derivative of the clutch actuation - Gungskoordinate according to the actuator coordinate is maximum.
  • the transmission is a double-clutch transmission, in which the clutches for the two partial transmissions of the dual-clutch transmission can each have the structure described above.
  • one clutch of the dual clutch transmission is closed and temporally overlapping the other clutch opened.
  • the clutch to be closed must not be actuated for safety reasons.
  • the clutch to be closed may only enter the closed state when the opening clutch has exceeded the so-called "kiss point", ie the actuation state in which the clutch discs are (still) touching, and no more torque is available through the clutch assigned sub-transmission is transmitted.
  • a first safety device can be electronically displayed and has two clutch position sensors, which are the current Monitor operating positions of the clutches and control the associated clutch actuators in response.
  • a mechanical safety device is proposed which prevents a simultaneous closing of the two clutches.

  • FIG. 1 shows the functional profile of a clutch actuation coordinate plotted over an actuator coordinate.
  • the two coordinates can be forces, torques, adjustment paths, angles of rotation, or the like.
  • the clutch actuation has a linear course. Starting from an opening state, the two clutch disks contact each other for the first time in the so-called "kiss point.” Closing the clutch further finally achieves the closed state In such a conventional normally-open clutch, the clutch automatically opens from the closed state in the event of a system failure As can be seen from the curve, it is necessary to lock the coupling in order to provide a permanent locking force.
  • FIG. 2 shows the functional profile of the clutch actuation coordinate plotted against the actuator coordinate according to the invention.
  • the curve here consists of two sections of linear curve sections, wherein the slope in the closed state is lower than in the open state.
  • FIGS. 3 to 6 show different functional curves, which are each composed of sectionally linear curve sections, wherein the gradient in the closed state is lower for each of the functional curves shown than in the open state and / or in regions between the open state and the closed state.
  • the slope of the curve in the closed state can be selected so that the clutch remains closed, taking into account the friction of the clutch assembly in the closed state, even if the actuator exerts no locking force.
  • the curves shown in FIGS. 2-6 are continuous but not continuously differentiable since they are composed of straight sections. But they each have a section in which their slope is maximum.

Abstract

L'invention concerne un véhicule équipé d'une boîte de vitesses et d'un système d'embrayage présentant au moins les composants suivants : un embrayage, pouvant être amené d'un état ouvert au repos à un état fermé sous l'action d'une force d'actionnement ou d'un couple d'actionnement, un actionneur d'embrayage et un dispositif de transmission prévu pour introduire dans l'embrayage une force générée par l'actionneur d'embrayage ou un couple de rotation généré par ce dernier, respectivement comme force d'actionnement ou couple d'actionnement, une coordonnée d'actionneur étant convertie en une coordonnée d'actionnement d'embrayage selon une fonction de transfert prédéfinie. Selon l'invention, le système d'embrayage est conçu de sorte que le gradient de la courbe de fonction de la coordonnée d'actionnement d'embrayage, reportée sur la coordonnée d'actionneur, est plus faible lorsque l'embrayage se trouve à l'état fermé que lorsqu'il se trouve à l'état ouvert et/ou entre l'état ouvert et l'état fermé.
